Abstract

Background: Air medical transport services play a significant role in emergency situations by providing timely transfers of critically ill patients to medical facilities. This study aimed to investigate the mission characteristics of helicopter emergency medical services (HEMS) and the associated time intervals in a geographically remote region of eastern Iran. We also compared the prehospital times of HEMS and ground transportation to determine whether dispatching a helicopter is time-efficient.

Methods: This retrospective cross-sectional study was conducted at the prehospital emergency medical center in Gonabad, a remote area in eastern Iran. Data were collected using standardized electronic forms developed by the Ministry of Health and Medical Education (MOHME) in Iran. We analyzed the mission profiles and prehospital time intervals for all Gonabad HEMS missions conducted between 2021 and 2024. The mean activation time was compared to the national benchmark of three minutes, and the prehospital time intervals of air ambulances were compared to those of ground ambulances.

Results: From 2021 to 2024, there were 252 HEMS missions, transporting 265 patients. Of all 252 missions, 95 (37.7%) were primary missions, and 157 (62.3%) were secondary missions. The most frequent reasons for air ambulance dispatch were trauma, acute coronary syndrome, and strokes. The mean ± SD for HEMS activation time was 9.14 ± 3.63 min, significantly exceeding the national benchmark of three minutes. HEMS prehospital time was 49.73 ± 9.67 min. The comparison of prehospital time intervals indicated that air emergency services are more time-efficient than ground ambulances.

Conclusion: This study found that the mean activation time of air ambulances exceeded the national benchmark of three minutes. When comparing prehospital times for air ambulance and ground ambulance services, HEMS was faster than both ground scenarios. The current benchmark for helicopter activation time in Iran may need clarification and revision.

伊朗东部的直升机紧急医疗服务:时间间隔和任务概况的4年横断面研究。
背景:空中医疗运输服务在紧急情况下发挥重要作用,及时将危重病人转移到医疗设施。本研究旨在调查伊朗东部偏远地区直升机紧急医疗服务(HEMS)的任务特征及其相关时间间隔。我们还比较了HEMS和地面运输的院前时间,以确定派遣直升机是否具有时间效率。方法:本回顾性横断面研究在伊朗东部偏远地区Gonabad的院前急救医疗中心进行。使用伊朗卫生和医学教育部(MOHME)制定的标准化电子表格收集数据。我们分析了2021年至2024年间进行的所有Gonabad HEMS任务的任务概况和院前时间间隔。将平均激活时间与国家基准3分钟进行比较,并将空中救护车的院前时间间隔与地面救护车的院前时间间隔进行比较。结果:2021 - 2024年,HEMS共完成任务252次,运送患者265例。在所有252个任务中,95个(37.7%)是主要任务,157个(62.3%)是次要任务。使用空中救护最常见的原因是创伤、急性冠状动脉综合征和中风。HEMS激活时间平均±SD为9.14±3.63 min,明显超过国家标准的3 min。HEMS院前时间为49.73±9.67 min,院前时间间隔的比较表明,空中急救服务比地面救护车更具时效性。结论:本研究发现,空中救护车的平均激活时间超过了国家基准的3分钟。当比较空中救护和地面救护服务的院前时间时,HEMS比地面两种情况都快。目前伊朗直升机启动时间的基准可能需要澄清和修订。
